A STUDY OF TREE ADJOINING GRAMMARS Vijayshanker Ph.D. dissertation proposal 1:30pm June 9, 1986; Room 337, Towne Building The goal of this research is to study a grammatical formalism called Tree Adjoining Grammars (TAG's). The original motivation for TAG's was linguistic and subsequent work established their linguistic relevance. Our study consists of two parts. The first part deals with formal properties of TAG's: for example, closure properties ; automaton characterizing classes of string languages and tree languages generated by TAG's. In the second part of our study, we outline how a syntax driven scheme for providing compositional semantics of natural languages can be given with the Tree Adjoining Grammars. Committee: J. H.
